In this case, the .t passed but self-heal-daemon (which btw does not 
have any role in this test because there is no I/O or heals in this .t) 
has crashed with the following bt:

Program terminated with signal SIGSEGV, Segmentation fault.

Not able to find out the reason of the crash. Any pointers are 
appreciated. Regression run/core can be found at
